OK, so a while back now I was working on a business plan and stumbled across the website of a startup company offering a very intriguing product, a small wind and solar generator system. The product is about the size of a digital satellite dish and the basic unit is claimed to produce 300 watts and includes a 700 watt inverter. Being the impulse buyer that I am, I quickly purchased some of these units but sadly they still haven't arrived. I'm starting to worry that I've been duped. My question to the
And please save the lectures. I know I should have done the research before making the purchase but such is life. Trust me, your not illuminating the point any more than my wife already has...repeatedly.
